8.3.3 Host Interface

The host interface can be provided through a SPI, UART, or CAN-FD interface. In some cases the serial interface for industrial applications is transcoded to a different serial standard.

The IWR1843AOP device communicates with the host radar processor over the following main interfaces:

  • Reference Clock – Reference clock available for host processor after device wakeup
  • Control – 4-port standard SPI (peripheral) for host control . All radio control commands (and response) flow through this interface.
  • Reset – Active-low reset for device wakeup from host
  • Error – Used for notifying the host in case the radio controller detects a fault
